A number of overviews[1]}, [2]}, [3]}, [4]} and more
extensive collections[5]}, [6]}, [7]}, [8]}, [9]}, [10]}, [11]}
on predictions of hydride superconductivity are available. The achievement of RTS has
also stimulated extension of high pressure techniques and the enabling of additional
measurements, in step with improved analysis and interpretation of data.[12]}, [13]}
